A Comprehensive Guide: Installing Ubuntu Step-by-Step for Beginners

So, you’ve decided to try Ubuntu—a free, user-friendly, and powerful Linux-based operating system. Perfect choice! Whether you’re switching from Windows/macOS or installing Linux for the first time, this guide walks you through the entire process. Let’s get started!

Pre-Installation Checklist

1. Back Up Your Data
   • Save important files to an external drive or cloud storage. Better safe than sorry!
2. Check System Requirements
   • RAM: 4 GB minimum (8 GB recommended).
   • Storage: 25 GB of free space.
   • Processor: 2 GHz dual-core CPU or better.
   • USB Drive: 8 GB+ (for the installer).
3. Download Ubuntu
   • Visit ubuntu.com/download → Download the latest LTS version (e.g., Ubuntu 22.04 LTS). LTS = Long-Term Support (updates for 5 years!).
4. Create a Bootable USB
   • Use BalenaEtcher (Windows/macOS/Linux):
     1. Insert the USB drive.
     2. Open BalenaEtcher → Select the downloaded Ubuntu .iso file.
     3. Select your USB drive → Click Flash!

Step 1: Boot from the USB Drive

1. Restart your computer and enter the Boot Menu:
   • Windows: Hold Shift while clicking Restart → Troubleshoot → UEFI Firmware Settings.
   • Mac: Hold Option (⌥) during startup.
   • Common Keys: F2, F10, F12, or Esc (varies by manufacturer).
2. Select the USB drive from the boot menu.

Step 2: Start the Ubuntu Installer

1. Choose “Try or Install Ubuntu” to test Ubuntu first (no changes to your PC) or “Install Ubuntu” to proceed directly.
2. Language & Keyboard Layout → Select your preferences → Continue.

Step 3: Configure Installation Settings

1. Updates and Software:
   • ☑️ Download updates while installing Ubuntu (recommended).
   • ☑️ Install third-party software (for graphics, Wi-Fi, and media support).
2. Installation Type (⚠️ Critical Step!):
   • Option A (Clean Install):
     • Erase disk and install Ubuntu → Best for dedicated Ubuntu machines.
   • Option B (Dual-Boot):
     • Install Ubuntu alongside Windows/macOS → Ubuntu automatically partitions space.
   • Option C (Manual Partitioning):
     • Something else → For advanced users (create /, /home, and swap partitions).
3. Confirmation:
   • Review changes → Click Install Now → Confirm with Continue.

Step 4: Time Zone & User Setup

1. Where are you? → Click your location on the map.
2. Create Your Account:
   • Name: Your full name.
   • Computer name: e.g., yourname-ubuntu.
   • Username: Your login ID (lowercase, no spaces).
   • Password: Choose a strong one.
   • ☑️ Log in automatically (optional for home use).

Step 5: Complete Installation

• Relax ☕! Ubuntu installs in 10–20 minutes.
• When prompted, remove the USB drive → Click Restart Now.
